Abstract
Mach-Zehnder waveguide interferometers have been fabricated in silicon and operation has been demonstrated at lambda =1.3 mu m. The switching mechanism is based on the thermally induced variation of the refractive index of crystalline silicon. Modulation depths of 40% were obtained for switching powers of 30 mW and switching times of 50 mu s.
